Frequently Asked Questions
How many write cycles and what data retention does the 25LC160A-I/P guarantee?
The 25LC160A-I/P is rated for 1,000,000 write/erase cycles per byte location and guarantees a minimum data retention of 200 years. These figures make it appropriate for applications that update stored configuration or calibration data thousands of times over a product's lifetime while ensuring data persists safely through long storage or shelf periods.
What SPI clock speed does the 25LC160A-I/P support and how does this affect MCU selection?
The 25LC160A-I/P operates at SPI clock frequencies up to 10 MHz, which is compatible with virtually all embedded MCU SPI masters running at 3.3 V or 5 V. This high clock rate allows a 2 KB full memory read in under 2 ms, making it fast enough for boot-time configuration loading without slowing system startup even on 8-bit or low-speed microcontrollers.
For which low-cost embedded storage applications is the 25LC160A-I/P a preferred choice over internal MCU EEPROM?
In MCUs that lack built-in EEPROM or offer insufficient capacity, the 25LC160A-I/P provides 16 Kbit of dedicated non-volatile storage over a 4-wire SPI bus without occupying internal Flash. Its 8-PDIP package costs less than Flash-emulated EEPROM solutions in many MCUs, making it ideal for meter calibration, sensor offset tables, and device ID storage in cost-sensitive industrial and consumer designs.
